The P150 is a very good choice. Kymco is or was recently affiliated with Honda, and does use the GY6 engine. The confusion comes from all the companies out there useing cheap, Chinese made copies of the GY6. The made in China 150cc scooter that You can buy on Ebay for $1,200 uses the "clone" engine, and may get You 1000 miles before it self destructs. The Kymco engine will last a lot longer. I've SEEN P150's with 20,000 + km's them, and I've heard of scoots with twice that. I have had the Chinese one, now I have a P150. The Kymco is on the quality level with the Japenese scoots, way above that of the Chineese bikes. FYI, if You want to ride at Interstate speeds, You need a 250cc. My P150 does about 60 mph.
